- 摘要：Thin-layer chromatographic (TLC)-UV densitometric method is developed for simultaneous quantification of sinensetin and 5-hydroxy--6,7,3', 4'-tetramethoxyflavone (TMF) in Misai kucing capsules (Orthosiphon stamineus). Sinensetin and TMF are isolated from the leaves of local Orthosiphon stamineus. The TLC-UV desitometric quantification is performed by external standard method on silica gel plates using chloroform-ethyl acetate (60:40) as developing solvent and UV detection at 365 nm.The TLC densitometer, although yields slightly higher values than the other analytical methods, is preferred due to its simplicity, easy and low cost.
